ANTISLIPPING DEVICE.

rosasec.

1 b all whom it may concern lie it known that l, HELLEIK S. Bnnon, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented new and useful Improvements in Ant-islipping Devices, of which the following is a specification.

This invention relates to anti-slipping devices or attachments for boots and shoes, and it has for its object to produce a device of simple construction which may be readily applied to boots and shoes of different sizes.

A further object of the invention is to produce an adjustable anti-slipping device including two frame members which are adjustably connected together in such fashion as to enable the application and use of the v device in connection with boots and shoes of various sizes.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,Figure l is a top plan view showing a portion of a shoe to which the invention has been applied. Fig. 2 is a top plan view of the device detached from the shoe. Fig. 3 is a perspective view showing the frame members of the device separated. Fig. 4- is a sectional detail view taken on the line di in Fig. 2.

Corresponding parts in the several figures are denoted by like characters of reference.

The frame members A and B include side members and 16 that converge in one direction so that the frame members when as sembled. will present an approximately triangular appearance. A side bar 15 of the frame member A has an extension 15 that overlaps the frame member B which is pro vided with a recess 15 to accommodate such extension, and in like manner a side Specification of Letters Patent.

Serial No. 780,777.

ar 16 of the frame member B has an extension 16 overlapping the frame member A which is provided with a recess 16 to accommodate such extension. The frame members A, B also include cross bars 17, 18 provided with spokes or calks it), 20 which. are provided with apertures that are thread ed for the reception of a right and left threaded screw 21 having a wrench seat 22 located about midway between the ends thereof. The said frame members it, B are also provided with end bars 28, 24: which are preferably shaped to conform to the configuration of the sides of a shoe sole, as best seen in Fig. 1.; curved flaps 25, 26 are hingedly connected with said end bars for the attachment of straps 27 which may be connected together across the top of the shoe by means of buckles 28, as seen in Fig. 1.

The extension members 15, 16 of the respective frames are provided with slots 29, 30 which, when the frames are assembled, are disposed in parallel relation; the frame members are connected together by fastening members, such as rivets 31 extending through the slots 29, 30, and said fastening members may be extended downwardly so as to constitute calks, as shown. Additional calks 32 are mounted at the intersection of the side bars and end bars of each frame.

The frame members A and B are assembled togetl'ier and slidably connected by the fastening members 31 in connection with the screw 21 that extends through the threaded apertures in the calks 19, 20. It will be seen that by turning the screw 21, the frame members may be moved toward or apart from each other, thereby fitting the device to shoe soles of various sizes, the attachment being completed by the buckle straps 27.

lVhen applied to a shoe or boot, the improved device forms a safe and etlicient antislipping device, enabling the wearer to walk safely on icy or slippery roads and pavements. When not required for present use, the device may be readily detached by simply unfastening the buckles 28. Owing to the peculiar triangular shape of the device and to the fact that two flaps 26 having buckle straps 27 are connected with one side, the device will be held very securely on the sole of the boot or shoe to which it is applied, this result being also assisted by the fact that the end members of the device conform in some degree to the curvature of the shoe sole, thereby preventing longitudinal displacement of the device with respect to said sole.

Having thus described the invention, what is claimed as new, is

1. An anti-slipping device comprising slidably connected frame members having side bars converging in one direction, cross bars provided with spikes having threaded apertures, and a right and left threaded screw engaging said apertures.

2. An anti-slipping device comprising frame members, each having an extension overlapping the other frame member, said extension of each frame member being provided with a slot, the two slots being parallel, and each frame being provided with a fastening member guided through the slotof the other frame member; each of said frame members being provided with a spike having a threaded aperture; and a right and left threaded screw engaging said apertures. In testimony whereof I afix my signature in presence of two witnesses.
